Maintaining a list of automotive auction records isn’t exactly easy or straightforward. Every auction house wants to claim a record every time it has an astounding sale, but sometimes those records can come down to splitting hairs: Does the highest price paid for a one-of-37 competition version of a certain model with a manual transmission and drum brakes really warrant a record, or should we only concern ourselves with the high-level makes and models?

What’s more, collector car auctions take place across the globe these days, which means multiple currencies. If one auction sets a record in U.S. dollars, but another one sets its own record in British pounds and currency values fluctuate between the two auctions, which record counts?

Do we count premiums and commissions in the record price? Do we adjust for inflation? Do one-offs, race vehicles, and customs serve as adequate benchmarks when they demolish previous record prices?

Nevertheless, we’ve given it a shot, and after a few years of tinkering with the formula, we believe we’ve got it down pat enough to compile a list of all the collector car auction records we could confirm in 2015, in alphabetical order:
